I have a 2006 GT with about 35,000 miles on it. About a month ago the car started bucking while driving and the check engine light came on. Took it to the dealer, they replaced the gas pedal assembly and said that the problem was a sensor in the old assembly. About a week later turned on the car and it began idling very rough and the check engine light came on again. Somehow it corrected itself and the check engine light went out. Now today I am driving down the road and the car starts bucking again, engine is running rough, and engine won't rev past 2500 rpms. Luckily I was by my parents house, I can't even get home cause I live off a highway.

I tried searching but couldn't find anything. Any help would be greatly appreciated.....

So the dealer has had my car for 8 days. Replaced the computer but found out that was not the problem. Today had a more senior mechanic from subaru corporate to the dealership and they diagnosed that I had a clogged throttle body. they cleaned it out and said I should be good to go but if it happens again I need a new one throttle body and they cost $630...

Anyone have any experience with this? Preventative maintnence? Guy said it was not common at all.....

I don't trust this dealer at all and frankly I am losing my faith in the Subaru brand.

Don't blame Subaru for a stupid mechanic/dealers mistakes and misdiagnosis's.

If this was a huge problem we would be hearing about it a lot more on many cars. It sounds like it could be a number of things, bad sensor somewhere, bad/clogged injector(s), coil related issue, there are many things that could cause the symptoms you are experiencing.

Subaru replaced the throttle body in the March. It was covered under warranty luckily. The car worked perfectly for a few weeks then the same problem happened. (No power, check engine light).

Brought the car in again and this time they determined there was a bad relay in the wiring system. Car worked for about a month and then a few weeks ago the same thing happend. I sent it to the dealer for a sixth time and they told me there was a loose prong in the new throttle body, they tightened it and so far the car has not broken down again.

I really like the car when it works but if this happens again I think I am going to contact a lawyer and look into the lemon law.

My dealings with the dealership have been great since I contacted Subaru Corporate. They always have a car for me to drive when they are fixing it. They are honest with me and have told me they have never seen this problem before. Since the first repair I have not had to pay for anything.

This is such a weird problem. Every time it happens within the hour the car works perfectly so it is hard for them to diagnos I suppose.

sounds like you been dealing with technicians (mechanic wannabes). took that long to fix a small problem. it was prob the bloody loose prong all along. i believe in pay once policy. if its the same symptom you shouldn't be paying more than once.

Well time for me to add to this. So 4 days after I got my outback xt the car threw me the cel and lost all power. Brought it into a parking lot and turned the car off for 5 mins. Started it back up and it drove just fine with the cel. Brought it to subaru and they checked the issue and apparently it "fixed" itself.

So now 4 weeks later I go to pick up my buddy at his house and about 400 feet from his house the car bucks wildly and i get the cel. So i drive it all the way home shifting from 1st to 5th cruising at 26 mph with my emergency flashers on. I did fly by a cop on the way home he just gave me a wierd stare and didnt do anything. But the car wouldnt rev about 2k while in nuetral and only 1k when in gear.

So I turn the car off and let it sit for a couple hours. And start it back up and it drives fine. I checked the code and it turned out to be P0123 - Throttle Position Sensor Switch “A” Circuit High Input. So I just reset that dang thing with my accessport and no problems. Its basically what subaru did to fix it in the first place, but this is just bad. I dont feel safe driving the car. Im going to mention it to the subaru dealers when I go there tomarrow to replace some shifter linkage, but theyll probably just dismiss it.
